The invention provides a skewed pole rotor and an assembly structure of a permanent magnet synchronous motor. A motor rotating shaft, a skewed pole punching sheet, a steel tile connecting piece, a connecting adjusting part, and a magnetic flux ring are provided. The surface of the motor rotating shaft is integratedly provided with a connecting key, and the surface of the connecting adjusting partis provided with an internal connecting hole, and the inner wall of the internal connecting hole is provided with a key connecting groove. The surface of the steel tile connecting piece is in the shape of an arc, and the inner wall of the key connecting groove is in threaded connection with a fixing bolt. The surface of connecting adjusting part is connected with the surface of the steel tile connecting piece through the fixing bolt. The invention relates to the field of motors. The skewed pole rotor and the assembly structure of the permanent magnet synchronous motor are advantageous in thatby setting up a magneto-resistance pad, and the magneto-resistance pad is convenient to calibrate the position relation during the angle adjustment of the skewed pole rotor, and therefore the problemsthat the skewed pole rotor of the general permanent magnet motor is easy to be interfered by the strength of magnetism to drive the rotating shaft to vibrate and generate noises when in use, and thecasting process of the skewed pole punching sheet is complicated are effectively solved.
Description
technical field [0001] The invention relates to the technical field of motors, in particular to an oblique pole rotor and assembly structure of a permanent magnet synchronous motor. Background technique [0002] When the permanent magnet synchronous motor is in use, complex space harmonic magnetic fields will be generated due to the limitation of pole slot matching selection, slot opening and local saturation, which will cause the induced voltage harmonics and torque ripple of the motor winding, which is not conducive to The smooth control and operation of the motor. In order to alleviate this problem, the permanent magnet motor usually uses a skewed rotor when designing. The current skewed pole is integrated. When it is disturbed by factors such as magnetism during use, When the oblique pole rotor is vibrated by the different magnetic interference of the stator bumps and grooves, it will also drive the heavier rotating shaft and other components to vibrate together, which w...
